I read of a zoo in Germany, which printed a 3D-prothesis for a raptor.
They bought it at e-Nable: http://www.socialtech.org.uk/projects/e-nable/
Here is the article http://www.stuttgarter-zeitung.de/inhalt.prothesen-fuer-tiere-greifvogel-soeckchen-und-das-bein-aus-dem-drucker.f907ce98-ed46-4936-9bdc-f4d9d7374587.html. It´s German, but maybe you can translate it with google.
I hope it will help you and Muse...
